Как организовать регистрацию пользователем почтового ящика на моем сервере?

This is only available for MailSuite Pro and MTA edition of Aurora. Signup and password reset are not available in AfterLogic WebMail or in web edition of Aurora, because these features don't work via standard email protocols and require direct integration with mail server.
The following options need to be set in /opt/afterlogic/html/data/settings/settings.xml file:
<AllowRegistration>Off</AllowRegistration>
If the value is set to On, a link to registration screen will be enabled on login screen.
